Is it not automatic via the Visualization menu?
Or do you mean that you would like it implemented for other systems? We implemented it using the JSON format file provided by Prof Vermeesch, but I think you could generate it by setting up your dataset, and clicking the "Save" button. If you send that to us, along with an example dataset, we'll add the template so that you don't have to do it by hand.
Kind regards,
